ISL83080EIBZ-T 收发器产品概述

一、产品定位与核心属性

ISL83080EIBZ-T是瑞萨电子(RENESAS)推出的1发1收RS422/RS485收发器,采用14引脚小外形集成电路(SOIC)封装,属于工业级通信接口器件。该产品专为工业环境下的串口数据传输设计,兼容RS422和RS485两种串行通信标准,支持点对点、多点总线等拓扑结构,可满足多数中低速工业通信场景的需求。

二、关键性能参数

该收发器的核心性能参数覆盖工业应用的基本需求,具体如下:

  • 工作电压:4.5V~5.5V单电源供电,无需双电源即可稳定工作,简化系统电源设计;
  • 数据速率:最高支持115Kbps传输速率,满足Modbus RTU等主流工业串口通信的速率要求;
  • 工作温度:-40℃~+85℃工业级宽温范围,可适应户外、车间等温差较大的恶劣环境;
  • 总线负载:支持最多32个RS485节点挂接,扩展能力符合工业总线通信的基本需求;
  • 共模电压范围:±7V(典型值),具备较强的共模干扰抑制能力,适合电磁环境复杂的工业现场;
  • 静态电流:典型值约1mA(接收器使能时),低功耗设计可降低系统待机功耗,适合电池供电或低功耗设备。

三、功能特性与优势

ISL83080EIBZ-T在功能设计上兼顾可靠性与易用性,主要优势包括:

  1. 多标准兼容:同时支持RS422(点对点)和RS485(多点总线)通信标准,用户可根据场景灵活选择拓扑结构;
  2. 单电源简化设计:仅需5V级单电源即可工作,无需正负电源转换电路,减少PCB布线复杂度与BOM成本;
  3. 高抗干扰能力:差分传输机制有效抑制共模干扰,结合宽共模电压范围,可在电磁干扰较强的工业环境中稳定传输数据;
  4. 总线保护功能:内置ESD保护(人体模式±15kV、机器模式±2kV),可有效防止静电放电对器件的损坏,提升可靠性;
  5. 独立收发控制:具备驱动器使能(DE)和接收器使能(RE)引脚,可通过外部逻辑独立控制收发状态,避免总线冲突;
  6. 低功耗待机:当收发器处于禁用状态时,静态电流进一步降低,适合需要低功耗待机的工业设备(如远程传感器节点)。

四、典型应用场景

ISL83080EIBZ-T的工业级特性使其适用于以下场景:

  • 工业自动化:PLC与传感器、执行器之间的Modbus RTU通信;
  • 楼宇自控系统:HVAC设备、安防摄像头、门禁系统的串口数据传输;
  • 通信接口扩展:工业计算机、嵌入式设备的RS485/RS422接口扩展模块;
  • 户外设备:远程监测站、智能电表等户外工业设备的串口通信链路;
  • 消费电子与医疗:部分需要稳定串口通信的工业级打印机、医疗监护仪数据传输。

五、封装与引脚说明

该器件采用14引脚SOIC封装(尺寸约8.65mm×3.9mm),引脚功能定义符合RS485收发器的标准配置,主要引脚包括:

  • 电源引脚:VCC(4.5V~5.5V电源输入)、GND(地);
  • 数据引脚:DI(驱动器数据输入)、RO(接收器数据输出);
  • 控制引脚:DE(驱动器使能,高电平有效)、RE(接收器使能,低电平有效);
  • 总线引脚:A(RS485/RS422差分总线正端)、B(RS485/RS422差分总线负端);
  • 空引脚:部分引脚为空(NC),可忽略或接地处理。

六、选型与设计注意事项

在系统设计中,需注意以下要点:

  • 拓扑匹配:若采用RS485多点总线,需在总线两端匹配120Ω终端电阻,抑制信号反射;
  • 电源滤波:建议在VCC引脚并联0.1μF陶瓷电容,提升电源稳定性;
  • 速率适配:若需更高传输速率(如1Mbps),可考虑瑞萨同系列的ISL83081等型号;若需更小封装,可关注SOIC-8封装的类似器件。

该产品凭借工业级可靠性、灵活的通信标准兼容及低功耗特性,成为工业串口通信场景的实用选型。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
